Talk to Sambino before taking off. Players can ask for a [Earthbind], [Stoneclaw], [Strength of Earth], [Stoneskin] or Earth Elemental Totem. Choosing one of the first three options will give players the requested totem along with one of the following responses:

The Great Sambino says: Jeeze... would you like me to have Felice give you a massage while you're at it? Here, take it. Go get me my sample!

The Great Sambino says: Well you're a picky little <race>, aren't you? Fine. Just go get me that sample.

The Great Sambino says: Wait a second... who's working for who here? If I give you the new totem, will you just finish the darn task?

Asking for a Earth Elemental totem, on the other hand...

The Great Sambino says: No. Stop being greedy.

Plant the totem at least 40 yards away from any other modified totems. A few crabs and eels spawn, then finally an Enormous Sand Crab will spawn. Kill the enormous crab, which has ~92,853 HP, to complete the quest.
